INTRODUCTION
The
Solomon Islands Ground Boas are members of the Genus Candoia. Candoia currently recognizes three species
of boas within this group. However,
taxonomic review may show five or six species, as being valid. These species
are as follows:
Solomon
Isle Ground boas - Candoia carinata
paulsoni
Halmahera
Ground boas – Candoia carinata ssp.
Solomon
Isle tree boas - Candoia bibroni
australis
Fiji
Boas – Candoia bibroni bibroni
New
Guinea Tree Boas – Candoia carinata carinata
Viper
Boas – Candoia aspera
Solomon
Ground Boas are small (3 – 4 ft.) boas that come in more than a dozen different
colors and patterns. They are unique,
beautiful snakes that have been overlooked and misunderstood for many
years. I will try to show you how to
maintain and even breed these fascinating island beauties.
Distribution
and Descriptions
Candoia
are distributed exclusively on islands in the South Pacific. Paulsoni are found
throughout the Solomon Islands in addition to many islands in eastern Indonesia
and offshore Papua New Guinea. These
snakes occur in many different habitats including dry savannas, forests and
wetlands. They also frequent areas of human dwellings where rodents are
abundant.
Each
particular island population seems to have their own forms and colors of these
animals. Santa Isabel is the largest
island in the Solomon Archipelago. It
is from Santa Isabel that the white boas originate. Although the same snakes as
other Paulsoni, these specimens are often referred to as Isabel ground boas or
simply Isabels. Paulsoni that are not
“white” come in many colors including red, pink, orange, gold, gray, brown, silver
and even black. Certain animals show a combination of 3 or 4 colors. These
individual specimens are awesome, with some having pinks, whites, oranges and
reds all fused together! In addition to
all these colors, these animals have the ability to change colors and to darken
or lighten up. These color changes are
gradual and are caused by many different factors, such as temperature,
humidity, cage-mates, time of day, etc.
All
Paulsoni have a characteristic zigzag stripe dorsally from head to tail. This
stripe is usually unbroken. It is also
darker than the snakes background color and varies in width. As with all Candoia, Paulsoni have thick
keeled scales that collect and retain dirt, dust and other residue more than
most snakes. They are at their most spectacular right after a shed. Isabel
ground boas are not white when freshly imported. It is with great anticipation
that I wait for a newly acquired Isabel to shed. Once these animals shed their
old dirty skin, what lies underneath is truly incredible. Some are actually
snow white! All ground boas, despite their names, have strong prehensile tails.
They will use branches if provided for them. Candoia seem to have a venomous
appearance, with flat, triangular heads and a squared off rostral scale similar
to a hognose snake. Candoia are mostly nocturnal.
Basic
Care and Maintenance
I
keep my ground boas between 80 and 82 degrees year round. Candoia in general do
not seem to require a hot environment. Humidity is kept at 50 – 70% with
occasional cage misting. I use several different types of cages for my animals.
An adult pair of Paulsoni can be kept in a 20-gallon long aquarium safely and
comfortably. I use newspaper as a substrate for all animals. It is simple and
easy to clean. Paulsoni love to soak, so a large water bowl is necessary. I
have often seen my animals copulate in their bowls. Candoia will defecate in
their bowls as well.
Because
of their slow metabolism, adult Paulsoni only need to feed every three or four
weeks. Babies and juveniles are fed more frequently. Large mice and weaned rats
are the main diet of captive Paulsoni. Some neonates will eat pinkies. Some
will only eat pinkies if scented with green tree frogs or anoles. A few babies
will hold out until the end and only accept live frogs or anoles. Stubborn
babies, like this, will eventually take pinkies after eating several scented
meals.
Breeding
When
kept at 80 degrees year round, your animals will need a 6 – 8 week cooling
period to initiate the breeding process. Drop the temperature to around 70
degrees at night and then back to 80 degrees during the day. This should be
done in November and December with introduction of animals in early
January. Although, not absolutely
necessary, I recommend using multiple males to insure breeding success. I have
many active breeding males in my collection.
I usually introduce two females to a group of four or five males. This
stimulates each male to pursue and breed with a female he is compatible with.
Certain males will breed several females, but not with all of them.
Occasionally a male may only breed with one particular female exclusively. Also
of importance, is that female Paulsoni should not be bred in consecutive
seasons. If your female produces a litter of babies, give her the next year
off. I am currently working with many different colors and morphs of Paulsoni
including the only known hypomelanistic specimen. I am looking forward to
continuing my breeding success with Candoia in the future.
Care
of Neonates
Ground
boas can produce large litters of young. Big females can have more than 50
babies at a time. Usually, 50% of neonates will take pinkies, but a supply of
small treefrogs or anoles may be needed to feed stubborn babies. Once a neonate
has eaten 4 or 5 meals it’s time to try scenting methods. It is best to wait
three or four weeks to make sure the baby is very hungry. When it sees a pinkie
that smells like its previous meals it is usually eaten immediately. You can
keep your neonates in plastic shoeboxes on paper towels with a small water
bowl.
Summary
Much
scientific fieldwork needs to be done on the Candoia genus. There are many more
things to learn about these diverse, beautiful boas. For instance, Halmahera
boas were only discovered in 1996 and many more Candoia could be awaiting discovery.
They seem to have a primitive, almost prehistoric aura about them. I have been
working with them for many years and am still learning new things every
day. They are easily affordable, easy
to maintain, colorful, and most are docile. Additionally, Candoia have many
interesting species to choose from besides the ground boas I have discussed
here. I hope you will give these
animals a second look and a second chance at being your next venture. You too can enjoy the many wonders of
Candoia, the Pacific Boas.
